Dear Anonymous Monk, it appears this will not work in Perl 5.8.8. The ?^ returns an error too. Well, sorry about that, I forgot about that (5.16 is my first perl in path), thats just the way it stringifies on the newer perls, you can simply ditch the ^
With actual 5.8.8 it stringifies as
(?-xism:(?-xism:(?:\<(?:(?>[^\<\>]+)|(??{$Regexp::Common::balanced [0]
+}))*\>)))
So here is the updated file, test still pass, with actual 5.8.8 too :)

No matter how hysterical I get, my problems are not time sensitive. So, relax, have a cookie, and a very nice day!

Will you please tell me what I am missing after I took all of the comments out? I'm still getting an infinite loop when these are nested with the error Use of uninitialized value in numeric gt (>) at files/lib/Base/HTML/Inline.pm line 32, <DATA> line 19.
Well, first thing is a call that calls the code .. word problems are hard :) when what is nested?

for my $loop ( 1 .. length $_ ){ ## guaranteed not to infinity loop
}
If there is infinity on the server, narrow down which data, which %ENV ... pepper in extra prints, narrow it down to a subroutine ...
